Abstract : A long-standing belief about injuries and diseases of the brain and spinal cord has been that once axons are destroyed, they will not re-grow. This belief is now being challenged. As the brain matures, the genetic programs that control axon growth during development are silenced. Recent evidence shows that re-activation of these programs in the adult successfully induces axon growth. We have shown that re-activation of Akt/mTORC1 signaling, by use of AAV vector transfer, induces regrowth of dopaminergic axons at 3 to 6 weeks after destruction by a neurotoxin. However, this approach cannot be used inhumans because Akt/mTORC1 signaling is oncogenic. The goal of this proposal is to refine this approach to achieve restorative effects in the absence of adverse effects.
